-Referring to the drawings'l is the frame of the machine and 2 are keys which bear the usual series of numbers for calculating purposes, each key having a large and asniall numeral in order that addition, subtraction a-nd division may be employed, in the ordinary way. The keys are arranged in longitudinal columns and transverse rows of digits with such digits in each longitudinal columnrunning from 1 to 9 of the major figures and from 8 to 0 of the minor figures The stems-3 of the keys of each longitudinal row, are mounted so as to slide vertically on fixed longitudinal bars 45 by means of slots 5 in the key stems and pins 6 engaging such slots and extending from the bars. Individual springs '7 connected to the'stems and pins serve to hold the keys normally in raised position. The stem has" a vertical extension or'arm 8 andv is turned at, right angles at its lower end to provide a heel 9, which is adapted to operate a sliding.

and oscillating angled'bar 10 connected to and adapted to operate the number wheel setting mechanism. (See Figs. 2 and 17). The number registering wheels (see Figs. 2, 16 and 17) are denoted by the reference character 11. The slide bar 10 is provided with two faces 12 and 13, and said slide bar is held normally in such position that the face 12 is tilted slightly upwardfrom a horizontal position. Aspring 1 1 connected .to the slide bar 10 serves to normally hold the'said slide bar in upwardly tilted position and witha notch 15,0f said. bar, in en gagement with a detent 16 in the bar 4}, whereby the bar 10 is held projected toward the number wheels.

"When a key is depressed the stem strikeswhereupon the bar is drawn toward the front end of the machine by a spring 17, connected at one end to the frame of the machine and at the other end to a link 18,

having a lug 19loosely engaging a slot in the bar 10 and connected at the other end'to the wheel setting mechanism. As the bar is ret'racted, a stop-tooth 20 in the bar will strike against the vertical arm 8 and stop the bar. A series of such stop-teeth are provided,

I one for'each key and they are so positioned relative to the keys, that the bar will move varying graduated distances according to xwhich key in one of the longitudinal digit series is depressed. Each end of the slide bar 10 has reduced swiveling andsupporting extension 21 extending through a hole in a tired plate 22, whereby the slide bar is eii'ectively supported at both ends and guided in a straight path. To the rear end of link 18 is pivotally connected a pawlcarrying arm 23 which is loosely mounted by means of a sleeve-on a main shaft 24, extending across the machine and ]ournaled 1n the side frames thereof. (See Figs. 2,3 and 4) Pivoted on this arm is a pawl 25 adapted to engage a gearwheel 26 also loosely mounted on the shaft 24. The teeth" of this gear wheel may either be of ordinary ratchet form or preferably may be ordinary curved,

spur gear teeth, with slight bevels, on the rear side at the'end to permit the pawl to arm.

' escaping from the gear ing arm for each number wheel and pawl.

move toward the front of the machine over them without engaging therewith. Aspring 27 serves to normally hold the pawl against the gear teeth, such spring being connected to a pin 28 extending from the pawl through an enlarged hole 29 in the pawl-carrying The gearwheel meshes with a pinion 30 carried by a sleeve 31 on which is also fixed the number wheel 11, which bears the numerals from O to 9, corresponding to and positioned relatively to the digits in thelongitudinal row of keys in .line with the wheel. 3

The pawl 25 has a shoulder 32 against" and all the driving arms are connected and operated by a common bail 35 engaging channels in the drivin arms and fixedly connected to the 'rotata le main shaft by means of arms 36. These driving arms when oscillated toward the back of the machine by the main shaft are adapted to pick up and, carry with them the pawl-carrying arms and thus actuatethe pawl so as to carry back the number wheel a distance corresponding to the number of teeth of the pinion and gear over which the pawl has been carried by the key-actuated slide bar.

On one end of the main shaft outside the frame is an operating lever 37 provided with a handle and pressed against by a return spring 38, which serves to return the lever to its normal, upright position after it has been operated by hand. 'By pressing. the lever downward, the driving arms, paw-ls and number wheels are actuated to register by these wheels, the numbers on the keys previously depressed. To this end, the pawlcarrying, arm 23 has a contact member consisting of a lug 39 extending from'the arm at right angles thereto, into the path of a rocker member 40, pivoted on the driving arm and having a shoulder 41 against which bears the lug 42 of a trigger 43 which is pivoted on the driving arm and has a pointed or beveled end at 44 (see Figs. 6, 7 5, 4 and 3). The rocker has a tooth 45, extending through an elongated arc-shaped slot 46 in the driving arm whereby the rocker is per mitted a limited range of movement with respect to the driving arm. A coiled spring 47 joins the trigger and an arm of the rocker and normally holds these parts in engage ment, keeping the trigger down against the shoulder of the contact arm of the rocker and the shoulder behind the lug of the trigger.

In registering any amounts below and in cluding 9, the proper key having been depressed and the pawl of the corresponding wheel thereby carried to the front of the machine, the proper number of teeth as determined by the particular key-stop on the slide bar, the handle-lever is depressed. until it comes in contact with a stop-pin 48, thereby rotating the main shaft 24 and by means of the bail 35-36, carrying toward the back of the machine all the driving arms 34 and the driving arm corresponding to the retracted pawl or pawls 25 will pick up the pawl carrying arms 23, by striking against the projecting contact lugs 39 and impel such arms so as to turn the corresponding gears .26 and pinions 30 and number wheels 11. To prevent the momentum imparted to the pawl carrying arm by the driving arm from carrying the former too far and thus turning another tooth of the gear and pinion, stop means for each pawl arm is provided, consisting of a lug 49 and a circular abutment collar 49' fixed on a bell crank member 50, which is mounted so as to oscillateon a fixed shaft 51, a bell crank member being provided for each pawl device. The end 23 of the pawl carrying arm is adapted to be limited in its movement against .overthrow by the lug 49 in registering numbers under and up to 9 (see Figs, 4 and 19).-

but does not abut positively against the lug,

moans? being separated therefrom by a slight space when the arm is in the thrown position, so

as to avoid friction w ien the lug is moved away and the pawl-carrying arm is thrown a tooth further in the operation of carrying the addition from ?9 to 10 from the wheel o1 the next lower column, as' will be described. The lug 19 is normally in. the

path of theend :23 of the pawl' carrier 23,

' lower wheel.

The carrying mechanism will now be described. Projecting forward from the upper part of the bell crank is an arm 52, with which is adapted to contact a rocker 53 on the side of the adjoining number wheel so that when the latter wheel has made a complete revolution and the 1O is to be carried to the next wheel'the arm 52 will be tripped which will momentarily rock the bell-crank and carry the stop. lug 49 out of the path of the pointof the pawl-carrying arm of the wheel of the higher series, (see Figs. and 19) whereupcn'the pawl-carryingarm of that higher series will be permitted to move forward farenough tocarry Y 'the pawl one tooth on the gear and thus turn the higher number wheel a space and carry over the addition. from the lower wheel. The rocker 53 is connected to a spring 135, which holds it normally in inoperative position against a stop-pin 136. See Fig. 12. A cam 137, either offset or 'formed by a slot, is provided on the partition plate 138. separating two adjacent number wheels and a pin 139 on the tail of the "rocker 53 is adapted tobear against this cam as the wheel approaches the-9 position so't-hat when the wheel reaches 9 the rocker will be tilted out sutliciently' to when it moves off the cam and its spring snaps it back to normal position and in so moving it hits the bell crank trip 52 and ing a short sets the bell crank corresponding to the next higher wheel for the 10 carrying position. The objects of this arrangement ,are to avoid the ob ections to a fixed pros.

jection on the wheel which are that owing to the liability of wear and consequent loose play of the 'mrts there is danger that theprojectionif positicned exactly at the point of coincidence of the trlp to carryover durmoving from *8 to 10, will whenbeing or average movement, as in carried to thet 9 position be thrown over far enough to improperly set the crank to 5 10, to avoid whichthe projection must be set -late on the wheel which involves the objection of a gossiblev failure to operate the trip on a short movement of the wheel. The carryingmovement is then effected by the point ozt' the trigger 4530f the driving ,ar1n-3 l of the higher wheel striking against the edge of a trip arm 54 on the bell-crank, wl'iich arm has been carried by the tilting of the bell-crank into the path of the trigger, thus releasing the rocker lO. See Figs. 5 and 19. It will be seen that the arm 52 of the bell-crank is actuated by one number wheel and the trip arm 5st, trips the trigger corresponding to the actuating parts of the wheel of the next higher decimal place. A spring pressed rocking lever 55 mounted on a shaft 56 projects into the path of the tooth 45 of the rocker 40 and is pressed by said tooth at each" actuating i'no'vement of the driving arm and upon the release of the rocker 10 from the trigger this lever throws the rocker against the pawl-carrying arm and the pawl thus impelled turns the gear a tooth and the number wheel to the next higher number. As the bell-crank is shifted to this carrying position, a hook 57 thereon, engages and is held by aspringpressed latch 58, mounted freely'on a shaft 59, and having a tail piece (30 so as to hold thebell crank in proper positicnduring the carrying operation.

A bail 61 extends across andimder the tail pieces and is pivoted on the shaft 59 and has an arm 62 pivotally joined to. a link 63. Thelink G3 has a pin which engages a cam slot 6 1 in a plate 65 carried by the main shaft and rocked thereby, by which connection the bail is adapted to release the latch 58 from the bell-crank hook. See Figs. 13 and To the other end of the link 63 is pivoted an arm 66 of a rocking bail (S7 contacting with. spring pressed detents 68, adapted to be carried by their springs into engagement with the gears upon the rocking in one direction of thebail through the main shaft and cam slot 64:, so as to thereby hold the gears from undue forward or registering movement, liable to be caused the possible rebounding of theslide bar as it strikes the key stem in its retracting move ment. Thedetents are withdrawn from the gears by contact of the bail immediately upon: the initial movement of the operating handle for the purposeof permitting the proper registering operation of the gears and wheels a .Mounted on the vupper part of the machine on a shaft 69-. are'springl-pressed de- .tents 70: alsow adapted to engage the gears and to prevent backward rotation thereof, particularly when the driving pawls are ratcheting into place w th the slide bar.

The bail 61 for the latches 58 and the bail 67 for the forward retaining detents 68 are linked together as shown and described, so that as one bail acts against the springs of its members, either latches or detents, the other bail moves away from the springs of its members and thus by having the springs of the two groups of members of substantially equal tension, with the tension of the one set opposed to that of the other, the operator in moving the handle is not obliged to exert extra power to overcome the force of either set of springs.

' Means are provided (see Figs. 1 and 16) to enable the amount indicated by a de- I pressed key or keys to be repeated in regisforced to rotate with it.

tering and such means comprise a small lever 76, mounted on a rocking shaft 77 which is provided with projecting pieces 78, adapted to strike against the transverse arm 79 of a sliding frame having longitudinal bars 80, which extend adjacent to and are guided by the bars on which the key-stems are mounted. These .bars 80 have struckout, ears 81, one for each key, extending through the slots 82 in the key-stem supporting bars, and adapted when the lever 72 is pulled backward, to be'carried by the sliding bars 80 overthe projections 83 of any keys, that-may be depressed, therebyholding the key'down and preventing the pawl arm actuating slide bars from-engagingtheir detents 16 so that the amounts indicated by the keys thus held down may be repeated by operating the main operating lever as many times as desired. Multiplica tion may be thus effected.

Extending upward through the frame. at the rear of the machine area series of error keys 841 pivoted to levers 85 mounted loosely on the main shaft and provided with arms 86. When a wrong key has been depressed and it is desired to correct the error before registering, the error key is depressed and therefore the arm 86 is lifted against the driving pawl so as to remove the same from engagement with the gear and carry the pawl backward to original position, which action at the same time releases the key from the slide bar and restores the slide bar to normal position.

To-enable the number wheels to. be re-set to O, the number wheel shaft is slidably mounted in the frame so that it may be slipped sidewise until spring pressed pawls 87 carried on the hubs 88 'of the wheels and projecting into the interior of the hubs, drop into grooves 89 in the shaft so that the wheels are then looked to theshaft and are The grooves 84 are made' slanting at each end in order that the pawls may readily slip into and out of the same. The wheels normally bear on the plain peripheral ortions between the rooves. The shaft 1s normally locked from acorns? mally in position with its smooth peripheral portions receiving the number wheels. To effect the resetting movement a pinion 96 1s fixed on the number wheel shaft at the left end thereof and adapted to engage this pinion but normally out of engagement therewith is a gear segment 97 carried by the main shaft. The pinion is brought into engagement with the segment by the sliding movement of the number wheel shaft. The main shaft being then actuated by the handle will turn the segment pinion and wheel shaft, until the hole in the disk at the right end snaps over the pin on the frame, which happens when the operating lever has completed its forward stroke and turned the wheel shaft completely around, so as to bring all the wheels to O.

In connection with the registering mechanism above described, I employ a recording mechanism which is preferably of the following construction. Pivoted at one end to each pawl carrying arm is a long link 98, the other end of which is intermediately pivoted to a printing wheel driving gear 99, which meshes with a pinion 100 carried 102 extends across the wheels and is adapted to be moved into locking engagement therewith upon the printing movement of the platen. It will be seen that as the pawl carrier is movedthe required number of-teeth corresponding with the depressed key, it imarts the same movement through the link 98 to the type wheel and thus brings the required number to printing position. Mounted beyond the printing wheel is a tilting carriage 103, upon an axis rod 104, having side pieces 105 held together by bolts 106 and 107. In this carriage is mounted on spring arms 108 a platen 109. The object of the resilience of the platen arms is to permit a slight yielding in case the car riage is not released exactly at the moment that the platen strikes the printing wheel. The carriage is shown at normal position with the bolt or bar 107 resting against a stud 110 rising from the base of the machine.

The carriage is tilted forward soas to rock the platen against the printing wheel by means of a link 111 pivoted at one end to a stud projecting out from the right side of the carriage. The link extends aior right hand side of the machine and z,

riage and impelling the platen against thev type Wheels. As the platen strikes the type Wheels, a.horn 117 carried by the carriage strikes against the detent bail 10:2 impelling the latter into engagement with the teeth of the type WhGQlS and firmly locking them during the printing impression. In its continued forward movement the link will be above the actuating cam 116, thus permitting the'plat'en and carriage to return to normal position. T his return of th s. carriage is quickened in order to insure the vvithdra ml of the platen trom the printing Wheel before the main shaft picks up the adding mechanism, by means of a lever 118 mounted on the pivot 119 at the side ofthe machine, and. havingv its loiver arm in. the path of a pinlZO projecting from the cam 11%. The upper. arm; ofthe lever extends into line with a pin 121 on the link. As the operat-. ing lever is continued invits forward and downward movement, the pin 120 will strike against the lower 21111101 the lever 118, moving the upper arm of the lever agaii -t the pin 121 thus throwing the link K sharply.

the link 18 and the paw 25 thereby set at the proper tooth on the gear 26 to rotate the number wheel to the proper numeral. At the same time the pawl-carrying arm will have drawn back the link 98 connected to the segmental gear 99, so as to set the corresponding type wheel at the proper numeral for printing. The operating lever 37 is tl 2n depressed by hand. so as to turn the nziin shaft This movement of the main shaftiirst moves the cam 116 into engagement with the projection 115 of the link 111 some to start the platen carriage on its hirivard printing movement. The actuation oi the carriage and the printing operation is completed before the lever moves far enough to effect the adding operation. At the beginning of its movement also the main shaft through it. earn-slot and hail 67 trees the forward looking detents. 68 from the gears, and carries the pawhlock 33 of the driving arm 3% into locking position.

To accommodate tins arrangement to the compactly arranget'i type vvheels,each link 15 pivoted to the platen. Any suitable inking an arm 132 pivoted on the shaft carrying the typevwheel gear segments. This arm is connected to a bar 133 at right angles to the arm and extending from. the end of an arc-shaped arm 134:, of the gear segment. The arc-shaped .arms of the gears in one or more series are successively placed in advance of one another, so that as the gears are operated the bars 133 may pass one another freely. Thus, the arm 132 farthest to the right of the machineand corresponding to the right hand column of number 'Wh66lS is connected to the bar farthest to ward the rear from the axis of the gear.- A series of five of the stepped arm gears may be arranged on the right hand side and a similar series on the left hand'side.

It will be seen that all these operations are efiected by the movement of the operating lever in one direction, by the force exerted by the hand of the operator.

It is necessary toreset the latches after each operation of the operating lever and before such lever is actuated again, otherwise with the latch holding the bell cranks in carrying position, the carrying would be continued. indefinitely. Hence the/bail 61 is so actuated by the cam slot as the operating lever is finishing its return stroke as to'lift the latches and then the springs on the bell crank return the latter to their normal positions.

, At the same time the forward locking detent or pawls' are returned to locking position.
